Rickochet It is just my personal preference but I never liked adding weight to a head. I instead always adjust the shaft flex fit the the head for a permanent fix.
These are different issues from what the OP garyt1957 asked about loading the shaft. On longer playing length drivers yes your opinion is correct for Rex and yourself but at normal playing lengths it is not valid IMO. I am speaking of 44" to 45" playing length drivers. It is the whole gamut of fitting factors not just shaft flex then add to that there is no standard flex across the golf industry it makes fitting yourself in a correct shaft a crap shoot. What works for one won't work for another.
Just me but I'd start with video to understand what I am actually doing. As far as being able to load shaft and "feel" shaft. See my release, tempo and transition.
I am also in the shorter playing length camp and hit solid center impact shots in the fairway rather than longer is better and spray and pray for the majority of recreational golfers especially on tighter tree lined parkland courses....open huge wide fairways bomb away.
When you get to become a senior male with under 90 mph driver club head speed the gains are not much between driver and a 3 wood. Lots of recreational male senior players and others for that matter can't get tee height correct for their launch angle with a 460cc head.
